Description

【0001】
【発明の属する技術分野】
本発明は、車両における乗降用ドア、とくに、製造上利点の多いドアの構造に関する。
【0002】
【従来の技術】
車両における従来の乗降用ドア1は、図3に例示されているように、それぞれドア1の輪郭を形成するアウタパネル2とインナパネル3とが車幅方向に間隔をおいて配置され、それらの車両前後端縁や下方端縁等の周縁部が相互に連結され、両パネル2、3の間に、ベルトラインリンホース4、ヒンジリンホース5、ラッチリンホース6等の補強部材が適宜配置されていると共に、ヒンジリンホース5に固着されたフロントブラケット7、7と、インナパネル3の車両後方側端部に固着されたリヤブラケット8、8とにより、それぞれサイドインパクトバー9、9の両端が固定されていて、サイドインパクトバー9、9がドア1全体の剛性を高め、かつ、車両衝突時にドア1が受ける衝撃を支持するように構成されている。
【0003】
しかしながら、この場合には、それぞれ個別に製作される補強部材やブラケット類の部品点数が多くなるので、各部品自体の精度及びドアにおける各部品の取付け精度を向上させるために多くの工数を必要とする上、各部品の管理工数もそれだけ増大することとなり、また、分散配置された補強部材によりドアの強度を効率良く確保させることが実際上容易でなく、さらには、ブラケット類の取付けに必要な接合部分が2重構造とならざるをえないため、ドア全体の重量を増大させることとなる結果、ドア1の製造に要するコストがかさむという問題があった。
【0004】
なお、車両用ドアとして、下記特許文献1に記載されたものが従来から知られている。
【0005】
【特許文献1】
特開2001−328430号公報
【0006】
【発明が解決しようとする課題】
本発明は、車両用ドアの製造コストを低減させようとするものである。
【0007】
【課題を解決するための手段】
このため、本発明にかかる車両用ドアは、ドア輪郭に略沿って環状に形成されたドアリンホースと、上記ドアリンホースの車室内側に配置されて上記ドアリンホースと車両前後方向端縁及び下方端縁がそれぞれ連結され上記ドアリンホースとの間に箱形断面が形成されたインナパネルと、上記ドアリンホースの車室外側に配置されて上記ドアリンホースまたは上記インナパネルと車両前後方向端縁及び上下端縁がそれぞれ連結されたアウタパネルとを有している。
【0008】
すなわち、ドアリンホースがドア輪郭に略沿って環状に形成されていて、このドアリンホースをベルトラインリンホースやヒンジリンホース等の補強部材、及び、ブラケット類として使用することができるので、ドアの製造に際して従来のようにベルトラインリンホースやヒンジリンホース等の補強部材、及び、ブラケット類を多数個別に準備する必要がなくなり、このため、部品点数を容易に、かつ、大幅に低減させることができて、単一部品である環状ドアリンホース自身の精度を高めることにより、ドアの各部精度を簡単に確保してドア製造の所要工数を低減させることができ、また、ドアリンホースが環状に形成されているので、ドアリンホースの剛性を容易に高めて、強度の大きいドアを簡単に製造することができるようになる。
【0009】
【発明の実施の形態】
以下、本発明の実施形態例について説明する。
図1において、車両用ドア10は、主として、ドア10の輪郭を形成するアウタパネル11と、ドア10の輪郭に略沿って環状に形成されたドアリンホース12と、上方に開口した略U字状のインナパネル13とから構成され、車室外側から順次アウタパネル11、ドアリンホース12、及び、インナパネル13が配置されている。
【0010】
また、ドアリンホース12及びインナパネル13の車両前後方向端縁及び下方端縁がそれぞれ溶接で連結されて、図2に例示されているように箱形断面14が形成され、ドアリンホース12及びインナパネル13によってドア10の骨格15が構成されている一方、アウタパネル11の車両前後方向端縁及び上下端縁がそれぞれ骨格15の外周端縁にヘム取付けされており、ドアリンホース12及びインナパネル13間の車幅方向隙間に図示しないドアウインドウガラスのレギュレータモジュールが配置されて、ドアリンホース12に取り付けられる。
【0011】
さらに、サイドインパクトバー16、16の両端がそれぞれドアリンホース12の車両前方側縦壁17及び車両後方側縦壁18に溶着され、車両前方側縦壁17に図示しないドアヒンジが取り付けられていると共に、車両後方側縦壁18に図示しないドアラッチが取り付けられている
【0012】
ドア10においては、骨格15の一方を構成するドアリンホース12が環状に形成されていて、従来のベルトラインリンホース4、ヒンジリンホース5等の補強部材が果たしていた機能を有すると同時に、両縦壁17、18がサイドインパクトバー16、16の両端をそれぞれ固定することができ、ドア10に必要な部品点数を従来よりも大幅に低減させることができるので、ドアリンホース12自身の精度さえ配慮すれば、ドアヒンジやサイドインパクトバー16、16等の取付け精度を自動的に高めることが可能となり、かつ、部品の管理工数も大幅に軽減させることができて、ドア10の製造に必要な工数を容易に低減させることができる。
【0013】
また、ドアリンホース12が環状に形成されているので、ドアリンホース12に加えられる負荷をドアリンホース12全体へ均一に分散させることにより、その負荷を効率よく支持することができて、ドアリンホース12の剛性を容易に高めることができ、それによってドア骨格15としての強度を確実に増大させることが可能となると共に、従来のようにブラケット類の取付けに必要な2重構造の接合部分が省略できることにより、ドア10全体の重量を軽減させることが可能となる。
【0014】
さらに、インナパネル13が上方に大きく開口した略U字状となっていて、従来のようにインナパネルがドアの輪郭を形成している場合と比較すると、重量を簡単に軽減化させることができ、この面からもドア10全体の重量軽減を図ることが可能となる。
【0015】
すなわち、部品点数や部品管理工数の低減、部品取付け精度の向上、ドア骨格15の強度増大、重量の軽減等によって、ドア10の製造に必要なコストを容易に低減させることができる大きな長所がある。
【0016】
なお、上記実施形態例では、ドアリンホース12が従来のヒンジリンホースをも完全に一体化しているが、ドアリンホース12成形上の都合等により、別体のヒンジ座金具をドアリンホース12の車両前方側縦壁17に固着するようにしても、上記実施形態例と同様な作用効果を奏することができるものである。
【0017】
【発明の効果】
本発明にかかる車両用ドアにあっては、ドアリンホースがドア輪郭に略沿って環状に形成されていて、従来のように補強部材やブラケット類を多数個別に準備する必要がなくなって、部品点数を容易に、かつ、大幅に低減させることができ、また、ドアの各部精度を簡単に確保してドア製造の所要工数を低減させることができると共に、ドアリンホースの剛性を容易に高めることができるので、ドアの製造コストを低減させることができる大きな長所がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a door for getting on and off a vehicle, and more particularly to a structure of a door having many advantages in manufacturing.
[0002]
[Prior art]
As shown in FIG. 3, in a conventional door 1 for a vehicle, an outer panel 2 and an inner panel 3 forming a contour of the door 1 are arranged at intervals in a vehicle width direction. Peripheral edges such as front and rear edges and lower edges are connected to each other, and reinforcing members such as a belt line hose 4, a hinge hose 5, a latch hose 6, and the like are appropriately disposed between the panels 2 and 3. At the same time, both ends of the side impact bars 9, 9 are fixed by the front brackets 7, 7 fixed to the hinge ring hose 5 and the rear brackets 8, 8 fixed to the vehicle rear end of the inner panel 3. The side impact bars 9, 9 are configured to increase the rigidity of the entire door 1 and to support the impact received by the door 1 at the time of a vehicle collision.
[0003]
However, in this case, since the number of components of the reinforcing members and brackets manufactured individually increases, a large number of man-hours are required to improve the accuracy of each component itself and the mounting accuracy of each component in the door. In addition, the number of man-hours required to manage each part increases, and it is not easy to secure the strength of the door efficiently by the distributed reinforcing members, and furthermore, it is necessary to attach the brackets. Since the joining portion has to be of a double structure, the weight of the entire door is increased. As a result, there is a problem that the cost required for manufacturing the door 1 increases.
[0004]
Note that, as a vehicle door, a vehicle door described in Patent Document 1 has been conventionally known.
[0005]
[Patent Document 1]
JP 2001-328430 A
[Problems to be solved by the invention]
The present invention seeks to reduce the manufacturing cost of a vehicle door.
[0007]
[Means for Solving the Problems]
For this reason, the vehicle door according to the present invention includes a door ring hose formed annularly substantially along the contour of the door, and the door ring hose disposed on the vehicle interior side of the door ring hose and an edge in the vehicle front-rear direction. And an inner panel having a box-shaped cross-section formed between the door ring hose and the door ring hose and a door ring hose or the inner panel disposed outside the cabin of the door ring hose. And an outer panel having upper and lower edges connected to each other.
[0008]
That is, the door ring hose is formed in an annular shape substantially along the contour of the door, and the door ring hose can be used as a reinforcing member such as a belt line ring hose and a hinge ring hose, and as brackets. It is not necessary to prepare a large number of reinforcing members such as belt line phosphorus hoses and hinge phosphorus hoses and brackets individually in the conventional manufacturing process, so that the number of parts can be easily and significantly reduced. By improving the accuracy of the annular door ring hose itself, which is a single part, it is possible to easily secure the accuracy of each part of the door and reduce the required man-hours for door manufacturing. Therefore, the rigidity of the door ring hose can be easily increased, and a door having high strength can be easily manufactured.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
In FIG. 1, a vehicle door 10 mainly includes an outer panel 11 that forms the contour of the door 10, a door ring hose 12 that is formed in an annular shape substantially along the contour of the door 10, and a substantially U-shaped opening that opens upward. The outer panel 11, the door hose 12 and the inner panel 13 are arranged in this order from the outside of the cabin.
[0010]
In addition, the vehicle front-rear direction edge and the lower edge of the inner hose 13 and the inner panel 13 are respectively connected by welding to form a box-shaped cross section 14 as illustrated in FIG. While the skeleton 15 of the door 10 is constituted by the inner panel 13, the outer edge of the outer panel 11 in the vehicle front-rear direction and the upper and lower edges are respectively attached to the outer peripheral edge of the skeleton 15 by a hem. A door window glass regulator module (not shown) is disposed in a gap between the motor vehicle 13 and the vehicle 13 in the vehicle width direction, and attached to the door ring hose 12.
[0011]
Further, both ends of the side impact bars 16, 16 are welded to the vehicle front vertical wall 17 and the vehicle rear vertical wall 18 of the door ring hose 12, respectively, and a door hinge (not shown) is attached to the vehicle front vertical wall 17. A door latch (not shown) is attached to the vertical wall 18 on the rear side of the vehicle.
In the door 10, a door ring hose 12 constituting one of the skeletons 15 is formed in an annular shape, and has the function of a reinforcing member such as the conventional belt line ring hose 4 and hinge ring hose 5, and has both functions. Since the vertical walls 17 and 18 can fix both ends of the side impact bars 16 and 16, respectively, and the number of parts required for the door 10 can be greatly reduced as compared with the related art, the accuracy of the door ring hose 12 itself can be reduced. With careful consideration, it is possible to automatically increase the mounting accuracy of the door hinges and the side impact bars 16, 16, etc., and it is also possible to greatly reduce the man-hours required for parts management, and to reduce the man-hours required for manufacturing the door 10. Can be easily reduced.
[0013]
In addition, since the door hose 12 is formed in an annular shape, the load applied to the door hose 12 is uniformly dispersed throughout the door hose 12 so that the load can be efficiently supported and the door hose 12 can be efficiently supported. The rigidity of the phosphorus hose 12 can be easily increased, whereby the strength as the door frame 15 can be surely increased, and the joint portion of the double structure necessary for mounting the brackets as in the related art. Can be omitted, so that the weight of the entire door 10 can be reduced.
[0014]
Furthermore, the inner panel 13 is substantially U-shaped with a large opening upward, and the weight can be easily reduced as compared with the case where the inner panel forms the contour of the door as in the related art. From this aspect, the weight of the entire door 10 can be reduced.
[0015]
That is, there is a great advantage that the cost required for manufacturing the door 10 can be easily reduced by reducing the number of parts and the number of man-hours for managing the parts, improving the accuracy of mounting the parts, increasing the strength of the door frame 15, and reducing the weight. .
[0016]
In the above embodiment, the door ring hose 12 is completely integrated with the conventional hinge ring hose. However, for the convenience of molding the door ring hose 12, a separate hinge washer is attached to the door ring hose 12. Even if it is fixed to the vertical wall 17 on the front side of the vehicle, the same operation and effect as the above embodiment can be obtained.
[0017]
【The invention's effect】
In the vehicle door according to the present invention, the door ring hose is formed in an annular shape substantially along the contour of the door, so that it is not necessary to separately prepare a large number of reinforcing members and brackets as in the related art, and parts The number of points can be easily and significantly reduced, the accuracy of each part of the door can be easily secured, the required man-hours for door manufacturing can be reduced, and the rigidity of the door ring hose can be easily increased. Therefore, there is a great advantage that the manufacturing cost of the door can be reduced.
